Issues running RastNus-Base-12B for Text-Only Kurdish Grammar

Error Correction

Hi Pawan,

I am testing the PawanKrd/RastNus-Base-12B model locally using HuggingFace Transformers for Kurdish Grammar Error Correction (GEC).

I am encountering non-deterministic and erratic outputs when passing text-only prompts. Here are the specific issues:

Coordinate / Tag Output: When prompted with simple Kurdish text, the model often returns bounding box coordinates or verification tags (e.g., 4 (5), Rast, 1 (0), R-C1234...) instead of corrected natural language sentences.

Base / Chat Template Behavior: Using processor.apply_chat_template or custom GEC prompts (Şaş: ... \nRast:) results in empty HTML tags (...) or classification labels rather than sequence-to-sequence text rewriting.

Pipeline: I am running the model with bitsandbytes 4-bit quantization on an RTX 4050 (6GB VRAM) via AutoModelForMultimodalLM and AutoProcessor.

Could you please clarify:

What is the exact expected prompt/template structure or task prefix for text-only GEC?

Is an input image mandatory due to the underlying PaliGemma-2 architecture?

Was this model fine-tuned as an end-to-end text rewriter, or is it strictly a error detection / token-tagging classifier?

Thanks for your work on Kurdish NLP!
